Definitions

  • the diffuser ring is displaceable with respect to the front part of the engine in the longitudinal direction of the latter, so that the inlet cross-section of the outer suction water jet enveloping the driving water jet is adjustable.
  • annular duct 90 is connected via pipe 82 with the suction line 81 of driving water pump 80, whilst 81a and 82a are valves.
